I grew up in LA, and have lived behind the Orange Curtain, and that's my point. The area is way too large in geographic area and demographics for me to believe the folks there are buying fixies in ways that exceed the mean.
It's far easier for me to wonder if they mixed up the data.
Almost by definition, a very large place with a very large population should have regressed to the mean, not far exceed it.
I live in San Clemente (a city of ~60,000 in Orange County) now, and was born in Pasadena. I was starting to get annoyed at OC being treated as one "city" here too, then I realized I should probably just be happy that a distinction between LA and OC was made at all. All too often, "LA" is used to mean everything south of Santa Barbara and north of Oceanside.
